To all? whom it may concern:

Be it known that l, :HAROLD' D. CHURCH, a citizen of the United States, and resident of Betroit, Wayne County State of Michis have invented certain new and useful improvements in Motor Vehicles, of which.-

the following is a specification.

This invention relates to motor vehicles particularly to the axle and wheel parts to thereon @ne of the objects of the invention is to provide an axle and wheel structure having simple demountable means for the wheel and a driving gear connection permitting easy removal or the wheel without disturbing the gear mounting. I

Another object is to provide casing means for a reduction gear axle to retain oil around the gears and remain intact when e the wheel is removed Another object is to provide e huih-up wheel of novel and strong construction, such as may be used. for instance on heavy commercial vehicles.

Another object is to combine a built-up wheel structure with a detachable wheel and axle of novel form thus obtaining various advantages hereinafter pointed out Other objects of the invention will appear from the following description taken in con-' neotion with the drawings, which form a part of this specification and in which the figure represents a sectional View through v a driving axle and wheel embodying the invention. v

Referring to the drawing, 1 is a supporting axle shown as having a spring pad 2 keyed thereto and a spring 3 connected to the pad. The spring pad is extended in the form of allange 4: which forms one of the wells of an enclosure or casing for the gearing hereinafter described. This flange also supports in bearings 5 the outer end of a driving axle shaft or section 6 enclosed by a tube 7 and preferably extendinr from a differential (not shown) at the midc 1c of the axle. The shaft 6 extends out o. :ndly locvond the flan e 4 rind has a pinion or gear 8 keyed or t erwise fastened to its end to turn with it.

The supporting axle .1 above referred to extends beyond the spring ad in the form of a spindle 9 upon whic are separated bearings 10 and 11 adjusted axially by a nut 12 threaded on the end of the spindle.

Upon these hearings the vehicle wheel is mounted, said wheelcomprising inner and outer separable hubs, the inner of which is put on the spindle with the bearings and the outer of which is detach-ably secured to the inner hub so that it may be readily demounted therefrom Without disturbing the bearings.

The inner hub is in the form of a sleeve 13 directly supported by the bearings and 11. At its inner end a packing'ld is provided to retain the lubricant in the bean lugs and a flange 15 forms an abutment or stop for the outer hub 16 and its driving gear 1 This driving'gcar 1.7 meshes with and is driven by the pinion 8 and it may -be as shown, formed to slide on the sleeve 13 to its position against the abutment 15.

T he outer hub 16 01 the wheel also slides on the inner hub or sleeve 13 .to which it is the bearings.

To complete the enclosure or casing of the gears 8 and 17 so that they may run in an oil batln a casing member 22 is provided, hemp detachably secured to the casing part or flange 41- as by a series of screws 23. This casingmember extends on the outside of the gears 8 and 17 and makes a running joint with the hub of the gear 17 as by the pacln inp; This is just inside of the clutch teeth 19 so that the hub 16 may be with drawn or removed from the sleeve 13 without disturbing the packing. This arran emcnt also brings the joint rather close to tie axis of the rotating parts so that considerable oil may beczu'ried'in the casing without leaking ou The wheel hub 16 above referred to is formed with a flange 25 to which the other partsof the built-up Wheel are secured. The flange has a series of studs 26 riveted in place as shown and a clamping plate 27 and series of nuts 28 cou'iplcte the fastening means. By forming the clamping plate 27 of dished shape as shown the nuts are brought out nearer the outer end of the huh where they are more accessible and the side strains on the wheel are transmitted to separated parts of the hub 16 instead of having them all taken by the flange 1Z5. Sleeves :3? are secured in place in the plates .27 to guide the studs as the wheclparts are put. together.

Two plates or disks 29 and 30 having their middle parts arranged face to face and their outer parts separated in somewhat conical form, have suitable openings for the studs 26 and may be placed on over the hub 16 against the outer face of the flange 25 and clamped between the latter and the plate i by the nuts .28. The disks 29 and i are each tapered in cross section towards the circumlererure and a rim, shown as formed of four parts 31, 32. 33 and 34. is secured to them as by the bolts 35. Attire rim 36 and tire 37 are suitably secured to the other rim. There is also a brake flange 38 secured to the wheel rim and its inner surface makes a running pa ked joint with the circumference ofthe flange l as at 39.

Other forms of the invention than the par ticular one shown herein may be used without departing from the spirit or scope thereof.
